[0022] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0023] like Figures 1 to 3 As shown, an embodiment of the utility model provides a container cargo blocking structure, which is installed on an insulated container 100 and includes an upper track 1, a plurality of floors 2, a lower track 3, and a cargo blocking rod 4.

[0024] The upper rail 1 is fixed on the top plate 101 of the container 100 and is provided with an upper mounting hole 11, which passes through the upper rail 1 and has a plurality of them, and the plurality of upper mounting holes 11 are distributed along the longitudinal direction. Specifically, the upper rail 1 is riveted to the top plate 101 by rivets and extends along the longitudinal direction of the container 100. In this embodiment, the upper rail 1 is plate-shaped and its upper surface is concave downward to form a positioning groove 12. In the transverse direction X of the container 100, the upper rail 1 forms a connecting plate 13 on both sides of the positioning groove 12, and the two connecting plates 13 are tightly fitted with the top plate 101 and are riveted to the top plate 101 by rivets. The inner bottom wall of the positioning groove 12 is provided with the upper mounting hole 11 downward, and the upper mounting hole 11 passes through the outer bottom wall of the positioning groove 12 downward.

[0025] A plurality of floor panels 2 are fixed to the bottom frame 102 of the container 100 by screws. The floor panels 2 are wooden floors 2. The plurality of wooden floors 2 are arranged along the transverse direction X of the container 100 and extend along the longitudinal direction, wherein the transverse direction X is perpendicular to the longitudinal direction. An installation groove 21 is formed between two adjacent floor panels 2, and the outer side walls of the two adjacent floor panels 2 close to the installation groove 21 are respectively recessed outward relative to the installation groove 21 to form a clamping groove 22.

[0026] The lower rail 3 is fixed in the mounting groove 21 and extends in the longitudinal direction. The lower rail 3 is provided with a lower mounting hole 31 corresponding to the upper mounting hole 11. There are multiple lower mounting holes 31, and the multiple lower mounting holes 31 are evenly distributed in the longitudinal direction. One lower mounting hole 31 corresponds to one upper mounting hole 11. The lower rail 3 has a fixing portion 32 fixed to the top surface of the bottom frame 102 on opposite sides, and one fixing portion 32 is clearance-matched with a slot 22, so that the slot 22 has a clearance space. The clearance space allows the fixing portion 32 to have a certain processing and assembly tolerance. When the fixing portion 32 is warped, it can prevent the inner wall of the slot 22 from interfering with the fixing portion 32 and causing the position of the floor 2 to deviate from the normal position, that is, it can avoid the situation that the floor 2 is uneven due to the uneven fixing portion 32, thereby ensuring the flatness of the ground of the container 100, which is conducive to the storage of goods, and the cargo blocking structure has the characteristics of simplicity and convenient assembly.

[0027] There are multiple cargo blocking rods 4, and the upper and lower ends of the cargo blocking rods 4 are respectively matched with the upper mounting hole 11 and the lower mounting hole 31. In order to facilitate disassembly and assembly, specifically, the upper and lower ends of the cargo blocking rods 4 are respectively matched with the upper mounting hole 11 and the lower mounting hole 31 with a clearance. In this embodiment, the middle parts of the end surfaces of the upper and lower ends of the cargo blocking rods 4 protrude to form an upper convex portion 41 and a lower convex portion 41, respectively, and the upper convex portion 41 and the lower convex portion 41 are respectively matched with the upper mounting hole 11 and the lower mounting hole 31 with a clearance.

[0028] The lower surface of the fixing portion 32 fits tightly with the top surface of the base frame 102. Specifically, the fixing portion 32 is plate-shaped and its lower surface is welded to the top surface of the base frame 102. There is an installation gap between the upper surface of the fixing portion 32 and the top surface of the slot 22, and the installation gap is D1. There is an installation spacing between the end surface of the fixing portion 32 and the inner wall of the corresponding slot 22, and the installation spacing is D2. When the lower rail 3 is positioned stably, ensure that the slot 22 provides as much space as possible for the fixing portion 32, and set D1≤1.3mm, D2≤6.9mm. In this embodiment, D1=1.3mm, D2=6.9mm. At this time, the values ​​of D1 and D2 are preferably. In other embodiments, the values ​​of D1 and D2 can be selected according to actual conditions.

[0029] In this embodiment, the lower track 3 has a plate portion, which is recessed upward to form a main body portion 30 that is clearance-matched with the mounting groove 21. The top surface of the main body portion 30 is downwardly provided with the lower mounting hole 31 that passes through its bottom surface. The plate portion forms a fixing portion 32 on opposite sides of the main body portion 30, respectively. The lower track 3 forms a groove 301 on the main body portion 30, and the opening cover of the groove 301 is provided with a sealing plate 33. The sealing plate 33 is welded to the main body portion 30 to form a sealing structure with the lower track 3, and the lower plate surface of the sealing plate 33 is welded to the top surface of the bottom frame 102, so that the lower track 3 is firmly connected to the bottom frame 102.
